Superior Refrigeration 586WA-8ST Ball Valve

The Superior Refrigeration 586WA-8ST Ball Valve is a professional-grade flow control solution engineered for high-pressure HVACR environments. This 1/2 inch ODF refrigeration ball valve features a robust forged brass body and a robotically welded joint design to ensure a leak-free hermetic seal across the entire service life. Designed for non-directional flow, this valve allows for versatile positioning within suction, discharge, or liquid lines. The Teflon full port construction provides a completely unrestricted flow path, minimizing pressure drop even in demanding industrial applications. Rated for a maximum working pressure of up to 700 PSIG, it is fully compatible with modern refrigerants, including R-410A and CO2. The dual stem seal design leverages Teflon packing with a secondary seal for redundant leak protection, making it a reliable choice for contractors managing HVAC fluid control systems where performance under thermal stress—from -40°F to +325°F—is required.

Key Benefits

• Full Flow Configuration: Large-diameter internal port eliminates turbulence and ensures maximum system efficiency.
• Dual Seal Technology: Features a primary Teflon seal backed by a secondary metallic seal, critical for preventing leaks during compressor burnouts.
• Bi-directional Operation: The forged brass ball valve functions reliably regardless of flow direction, simplifying installation in complex piping.
• Internal Forged Stops: Mechanical stops provide a precise 1/4-turn operation for positive open and closed positions.
• Extended Copper Tails: 1/2" ODS connections allow for easy brazing without the risk of overheating internal valve components.

Common Questions

What refrigerants are compatible with this valve?
The 586WA-8ST is rated for use with most HFC, HCFC, and CFC refrigerants, as well as R-744 (CO2) and R-410A.

Can this valve be serviced in the field?
This is a hermetically welded, non-serviceable valve designed for long-term reliability. The unique seal cap allows for valve operation without cap removal, preserving the primary seal integrity.

Does this model include a Schrader access port?
The 586WA-8ST (WA series) is the standard version without an access fitting. For models with an integrated access port, refer to the WAS series.
